My LM4 will be here Friday, I wont touch it till Saturday morning, and that will be briefly. I'm going up to a local field Sunday for some field time but, I wont be using my LM4 until I can get it stripped down and thoroughly checked, cleaned, and oiled up. So that won't be until after the game when I can get back to my wholesalers shop and use his tools.

My question is not just for me, but for others who purchase the gun and want to make sure she's perfect before use. What are somethings I should look for and check on, areas that need more cleaning and such. Should I use both spray and liquid silicone? What are common areas items that there has been "gunk" that needs cleaned up?

I ask because I want to do everything I can to keep it as well maintained as humanly possible.

Just do the regular and clean the inner barrel..don't get silicone oil on bucking tho.. I wipe off all the factory lube and clean it and then lube with silicone oil.lube down all moving parts. With a thin layer of silicone oil or shock oil. Oil the oring in the bcg. And also oil the roller on the hammer. My rule of thumb is if it moves it needs lube. Check the other threads..it'll show you in detail how to take it apart..

DONT USE SPRAY SILICONE. Please just don't. You may want to clean the inner barrel and hop up area with a clean Q-tip and the cleaning patch just to make sure there is no dirt from transit. This is what I will be doing when I get my LM4 tomorrow. Unlike you, I plan on fielding it the next day lol. We'll see how that goes, I bought 4 spare mags

Welcome to the LM4 owners club(or soon to be). What I did was downloaded and read the manual before my gun came in to get all the info I needed before it came. The PDF manual can be found: http://kwausa.com/fi...MD23_LM4PTR.pdf

There are two set screws on the outer barrel very close to the delta ring. I would advise that you put a mild thread locker on these set screws. Mine came a little loose after firing the LM4 for a while and the hop up/inner barrel would have a little play if these come loose. For anyone reading this that has LM4 jamming issues: this might be the reason your gun is jamming and tightening the screws might solve that problem. The screws are the the 12 o'clock and 6 o'clock. You might want to move the gas tube out of the way to properly tighten the one at the 12 o'clock position.

I just got my LM4 yesterday (whoohoo!) and I cleaned and lubed her up last night I wouldn't worry too much, just do as these gents suggest and you'll be fine, Devil.

I was very surprised to find the inner barrel was very clean and I could barely gather any 'gunk' from the hop up area. I was expecting a lot more treasures to find after reading all these posts. I also went through all my magazines' release valve area, cleaning out all the metal shavings and factory lube. Relubed those bad boys and tossed them back in the magazine, tightening them to ensure a nice seal as per Allizard's post. Do all this and I'm sure you'll be good to go.

with that said goodluck devil and welcome to the LM4 club!

Thanks for the feed back. I know it makes the Mod's and Admin's jobs a whole lot easier.

So, using a RS cleaning kit would work for the inner barrel, correct? Also, how do keep silicone oil off the bucking if you clean the inner barrel? Noob question im sure. Only use liquid 100% silicone on all moving parts, and clean and lube all magazines. I wont be Fielding it sadly because I wont have time to thoroughly go over it before the game because I don't have any tools needed to do so yet. As for tools, my wholesaler has all them, so, I'll be using his shop after the game to do so. Unless he has all the tools in his mobile work shop. I absolutely appreciate everyone being so helpful.

A couple of things. If the RS cleaning kit uses a metal rod, DO NOT USE IT as it will scratch the inner barrel. Also, do not lube the magazine's loading chamber, the valves yes, not where the BB's go. It causes dirt to collect and can make the BB's foul and mag fail. 100% silicone, like that which came with the gun is best. If you run out 20-30 wt RC shock oil works fine. Niko and I are testing some Dry Lube and while I have yet to use it on my LM4 Niko has and the results are so far promising. More on that to come.

It should have came with a plastic cleaning/unjamming rod combo. One end has an eye to put a cloth patch through, the other end has a plastic tip slanted so you can unjam bb's from the barrel. I have never broken one.. but I could see someone getting a little crazy and breaking it. Just go easy and dont force it.

If your rifle did come with one I like to use .223/5.56 cleaning patches for the inner barrel. I cut them in half so they run through easier... as for your question about the bucking, I shine a flashlight into the chamber so I do not push the cleaning rod too far in and jam it up against the bucking.

To add to what Epitaph said, use a flashlight to point into the barrel from the hopup side, slide the cleaning rod into the gun, then what I do is take some yellow(or any color) tape and tape the rode where the end of the barrel is. That way for future cleanings you just push the rod in till the tape is at the end of the barrel and you know not to go any further.

I also have been using Winchester cotton patches p/n: 99718, I fold them in 1/2 and put them through the rode and it slides down the barrel very well. I also dip the first patch in water and use that to clean the barrel, then I go down 2-3 times more with a dry patches and the barrel is squeaky clean.
